SPRING MOTOR I Application filed March 29, 1929. Serial No. 350,855.

This invention relates to new and useful improvements in spring motors. The invention has for. an object the provision of a device of the class mentioned which is of simple durable construction, de-

pendable in use and efficient in action, and which can be manufactured and sold at a reasonable cost.

The invention proposes the use of a plurality of energy storing means supported withm a frame, and each means arranged to receive energy from a common'driver pinion adapted for connection with sources capable of delivering the same and all arranged to individually, '15 partiallysimultaneously,or completely simultaneously deliver the energy to a common driven pinion adapted for connection with sources intended to receive the same. The energy storing means should be arranged 0 with a spiral spring capable of holding the desired energy.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the follow- 1 25 ing description and accompanying drawings,

- a0 material part of this disclosure Fig. 1' is an elevational view of a device constructed according to this lnventlon.

Fig. 2 is a transverse vertlcal sectional I i view taken on the line 22 of Fig. 1.

Fig. 3 is a fragmentary sectional View of one of the spiral springs and associated parts used in the device.

Fig. 4 is a transverse sectional view taken on the line 4-4 of Fig. 3.

.49 The reference numeral 10 indicates gen-' erally a base plate upon which a frame is firmly mounted, said frame consisting of three transverse parallel plates 11, 12 and 13 held in spaced relations by spacer bars 14.

A standard 15 is mounted upon the base 10 and supports a shaft 16 carrying a Worm 17 meshing with a worm wheel 18 on ,a shaft 19 rotatively supported in the plate 11 of the said frame. A driver pinion 20 is secured upon the inner end of the shaft 19. A plurality of energy storing means 21 are mounted between'the plates lland 12, and are connectedfor receiving energy from the driver pinion 20, and delivering the energy to a driven pinion on a shaft 22 rotatively 55 mounted in the plates 12 and 13. The shaft 22 is provided with a pinion 23 on its outer end meshing with a pinion 24 on the shaft of energy receiving means 25 mounted onthe said base 10. I

Means for governing the steadiness of the power transmitted to themeans 25 is provided, and consist of a pinion 26 fixed upon the shaft'22' and meshing with a gear 27 on a shaft 28 rotatively mounted in the plate 13 and in a'bracket 30 secured upon the plate12. A circular rack 31 is mounted upon the shaft 28 and has several apertures 32 engageable by a plunger 33 slidably mounted in a block 34 attached upon the bracket 30. Screws 35 7o threadedly engage in the block 34 and serve to holdthe plunger 33 in a raised position free from any of the apertures 32 or in a position engaged inone of the said apertures. Each of the-energy storing means consists of a longitudinal shaft 36 rotatively supported between the plates 11 and 12 and provided with a ratchet wheel 37 firmly attached. A pawl 38 is mounted upon the plate 12 and engages against the ratchet wheel 37 80 for limiting rotation of the shaft 36 in one direction. A gear 39 is fixed upon the shaft 36 and meshes with the driver pinion 20. A hollow drum 40 is rotatively and slidably mounted upon the shaft 36, and at one end is formed with gear teeth 41 normally meshing with the said driven pinion 60. A spiral spring 42 is mounted within the hollow drum 40, and its outer end is fixed upon the inner periphery of the drum, while its inner end slidably engages upon a key 43 mounted in the shaft 36. The slidable engagement of the inner end of the spiral springand the key is accomplished by a transverse pin 44 projecting from the key into elongated slot 45 formed in the spring.

-The hollow drum 40 is provided with a grooved collar 46 at one of its ends, engaged by a fork 47 supported by a slidable bar 48 arranged for sliding in the plates 11 and 12.

One end of the bar'48 has a head 49 which limits its sliding in one direction and the other end has-a handle 50 arranged for limiting the sliding in the opposite direction. As" shown in Fig. 1, the gear teeth 41 en-' .gage the driver pinion 22. The handle 50 may be drawn towards the right, as indicated by dot enddash lines. 51 for moving the dr m towards the right as indicated bydotand dash lines 52 so that the gear teeth 41 are free from the pinion 60. In its new position the drum is held against rotation by astop 53 projecting from the spacer bar 14:.

In operation of the device, each of the handles are moved to the left so that the gear'teeth ii of; eaeh of the hollow drains en- 7 gage withthe vdriven pinion 60;.
